Empty vinyls that were recorded with silence were taped to the floor of a concert hall before the start of the show. During the live show, the audience unknowingly stepped and danced on the vinyl records. The scratched records were retrieved after the concerts and the sounds they made with a record player were mixed and turned into original tracks.
Project Bootleg recorded concerts by artists Die Antwoord, Gold Panda, The Roots, Apparat, and Deadmau5. You can listen to the first two tracks on the Ma Ma website.
